1'0 alt whom. iimay concern.-

Be a known that 1,- IIORACE E. HEN QO'D, a subject of the Crown of GreatBritain, and

' a resident of the borough of Manhattan, city of NewYork, county andState of New York, have invented certain new and useful Improvements inBedstead Attachments, of

which the following is a specification, reference being had to. theaccompanying drawings, forniing apart thereof.

"My invention relates to bedstead attachments, and particularly to meansadapted to be attached to an ordinary bedstead for converting the saidbedstead into a hospital'or invalid bed wherein the I patient may beraised from the mattress or other supporting surface for whatsoeverpurposes may be necessary. 1 p

' Myinvention comprises a stretcher, hoisting =Ineans therefor, anddirection-pulleys, including clamps, by which the said pulleys may beattached to the desired parts of bedsteads of different sizes.

My invention consists not only in' the general combination bywhich thesaid lifting mechanism may be. employed for bedsteads of differentsizes, but also in many details of construction in the lifting means,the direction-pulley supports. and the stretcher.

My invention also consists in providing. an

other opening, or other openings, in the fabric. employed as the portionof the stretcher bywhich the invalid is supported, in addition to theopening usually employed therein for toilet purposes.

In order that my invention may be fully understood, I will now describean embodiment thereof with reference to the accompanying drawingsillustrating same, and will then point out the novel features in claims.

The bedstead here shown is of the ordinary type of metal bedsteadscomprising a head 15, afoot 16, and side irons 1 7. l A mat-tress andspring 18 of ordinary form, such as the usual combined boX spring andmattressf-is 5 shown as supported by the bed frame.- The head 15 andfoot 16 are each of the typeha'v ing upper horizontalbars 01 heads 19,20, and are also provided with the usual lower frame irons 21. This isan ordinary form of bed such as is well known in the market, andi't isthe purpose of my present invention that such a bedstead may be used intheordinary 1 manner by a member or members of a family," but that, whendesired, such bedstead, bv'

theaddition of certain attachments, shall be readily converted into ahospital or inva-' lid bed, so that an ordinary domestic be'd-" steadmaybe converted'at will, and'with a minimum of, trouble, into an.invalid bed; To these ends I provide a stretcher compris ing a metallicframe 22, and a supporting fabric 23. The supporting frame 20 iscomposed of pipe lengths, which serve for the sides and ends thereof.The said sides and ends are connected together by corner pieces, one ofwhich is illustrated fullyin 1g. 7. prises an elbow 24;, shoulderedportions or abutments 25, and fingers 26 extending at right angles toeach other from the said 001'- ner piece. seen by reference to Fig. 7,are received within the ends of the pipe sections forming the side andendrods, the ends'oft-he saidpipe sections resting against the shouldersor abutments 25. portions or grooves 27 in the fingers 26 forthe purposeof receiving the shanks of buttons These fingers, as will be clearly Ipreferably provide slotted Each of these corner pieces com- A 5 the pipesections for the purpose of receiving the ends of flexible liftingbands, to be presently described. These 'grooves'or slotslper-l mittl1e4shanks of the buttons- 28 to be" screwed in further than wouldotherwise be" possible, so as to permit the buttons to have a furtherhold, and also serve to prevent the tube or pipe sections from turningwith respect to the corner pieces, when once the parts are securedtogether. This is important, as, if some such provision were not made,tension upon the lifting bands or straps would tend to turn the pipesections, and cause the said lifting bands to become detached.

The fabric 23 is fastened to the frame in any suitable manner,preferably by lacing 29, as shown. The elbow art 2.4 of the corner piecemay convenient y be provided with an eye portion 30, to which a portionof the lacing may be secured at the corners thereof, in order to holdthe fabric firmly in its proper position. This stretcher is arrangednormally to rest upon the mattress '18, and will not inconvenience .thepatient at all under such. circumstances, as the only extra thickness isthat of the fabric 23. The stretcher is arranged to be raised and lowered by means of flexible lifting bands or straps 31, 32, the free endsof which are connected to the stretcher frame by means of thebuttons'28, the intermediate portions passing over suitabledirection-pulleys, and the opposite ends of which are engaged by awinding bar or rod 33. The direotion-pul leys are mounted in clamps 34,(shown in detail in Figs. 2 and 3,) by means of which they may beattached to any desired part of the bedstead. These clamps comprise twomembers 35, 36, secured together by bolts 37 and wing nuts 38. The lowerends of the members 35 and 36 surround a directionpulley 39 supportedthereby, portions of the said members constituting bearings for thetrunnions of the said directionulley, and the upper ends of the said memers35 and 36 are curved, as is shown in the drawings, so that they willreadily embrace the tubing constituting the bars 19 and 20 of the bedstead foot and head frames, and this portion of the members is soshaped, also, that the said clam is equally adapted to be secured to therai s 21, as will be readily understood by reference to the drawings.Manipulation of the wing nuts 38 is all that is necessary to secure theclamps in position, either upon the tubing constituting the parts 19 and20, or upon the rails 21', and, by reason of the fact that each clampand roller 39 isa part independent of other clamps and rollers, the saiddevices may be attached at the desired points to bedsteads of differentwidths, sizes andshapes.

The winding mechanism comprises the member 33, above referred to,supporting clamps 40 and 41, and suitable gearing sup*.

ported by the clamp 40. The clam 40, and. gearing in connectiontherewith, is il ustr ated' fully in Figs. 4, 5 and 6, said clamp comprising two members 42, 43 secured together y means of bolts 44. andwing nuts 45, distance pieces 46 being emplo ed to prevent the partscontained between t e clamp memto the corner pieces employed bers ononesid 'ol the bolts 44 from being pinched. Upon the other side of thebolts 44, the members 42, 43, have parts 47, 48

arranged to embrace the posts 49 of the bedstead foot; Gearing,comprising a pinion 50 and a spur-gear 51, is arranged between the clampmembers, the axles of said pinions being supported by the said clampmembers. The axle of the pinion 50 has a projecting squared end towhichmay be attached an operating handle 52, while the axle of thespur-gear 51 is comprised in the winding bar or rod 33. This winding baror rod is prefer ably tubular inform, and is provided with a slot 53 forreceiving the lifting bands or straps 31, 32, such slot forming a meansby which the strap ends are caused to be fastenedto the winding bar orroller and positively rolled up'upon the same when the said bar orroller is rotated. This rotation may be accomplished by rotation of thehandle'52,

motion being' transmitted to the said wind ing bar or rod through thegearing 50, 51.

A pawl 54 maybe employed, if desired, .to

engage with the teeth of the pinion 50 thereby to act as a holding,means to hold the arts in the position to which they have been moved.Rotation in the proper direction of'the handle 52, and hence rotation ofthe winding bar 33, will result in lifting the stretcher to a position,such for instance as is shown in Fig. 1. In this position the patientwill have been liftedto a position some distance above the mattress, aswill be well understood, and, as the fabric 23 of the stretcher isrovided with the usual opening 55, a vessel may now be placed upon themattress 18 beneath the stretcher, for toilet purposes.

In order to give the patient greater comfort, I have provided a backrest 56 composed of a frame-work 57 and flexible fabric 58 securedthereto by lacing 59. The framework 57 comprises tube sections connected.together by corner pieces 60, guite similar stretcher frame. To'pivotally connect the side portions of the frame 57 with the stretcherframe, I have provided end members 61 (see particularly Fig. 9), saidend members provided with shanks 62 which extend inward within the endsof the pipe sections of the frame-work 57, and with trunnion pins.

63 adapted to be received within openings 64 in the stretcher frame 22.The trunnions 23 are preferably provided with projections 65, whichregister with enlarged portions 66 of the opening 64, said projections65 and enlarged portions 66 being so arranged axially withrelation toeach other as to col y come in line in an unusual or a forced positionof the back rest. Thus the back rest may be assembled into position withthe stretcher frame, but will normally be held against accidentalremoval therefrom. 'ut memor the main ber, comprising tubu'larsections67 and a connecting member 68, is provided, the sections 67 beingpivotally connected to the back rest frame 57 (see Fig. 12) in the samemanner that the back rest frame is pivotally connected to ,the stretcherframe, the part 68 arranged to cooperate with ratchet teeth 69 securedto the stretcher frame.

Theback rest may be swung u ,:into the required position, and supportein position by the strut member, as will be well understood. If, then,the patient is well enough to be su ported in a sitting position whenelevated y the means above referred to for the foregoing purposes, theback rest may first be adjusted in the approved-position. Then, tofurther promote the comfort and convenience of the patient, I haverovided openin'gs'ZO, in addition to'the usua o ening 55, in the fabric23, through which t e legs of the patient may be inserted, whereby thepatient maybe in an ordinary sitting position, and hence in afpositionbest adapted to I the requirements; 2 5 V In a former United StatesPatent, No. 802,756, granted to me October 24th, 1905, an attachment wasshown and illustrated adapted to be adjusted in position upon abedstead, but such attachment was suitable only for a bedstead of apredetermined width. It will be apparent from. the description andillustration herein that the present attachment is suitable forbedsteads ofdifferent widths, for the reason that the clamps carryingthe, direction rollers are independent units, and may be adjusted upon aedstead regardless of their relative positions. It 1s, 0; course,understood that for a wider bedstead a Wider stretcher frame Wlll benecessary, but it will be noticed that the only change 111 even thispart of the invention will be the revision of lon er v)i e sections for"the end pieces of the stretcher frame, and a correspondingly longerpipe-section for the upper member of the back rest frame 57. It willalso be understood that the novel feature comprised in the additionalopening or openings in the stretcher fabric 23 is applicable to otherforms of elevating devices, and that such feature may, indeed, beemployed wherevenstretchers of this character are used for acorresponding purpose.
